Title: Traverse grinding controller
Inventor: TAKADA NORIYASU
IPC: B24B49/04
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To shorten machining time and to improve accuracy by subtracting a dummy grinding amount obtained by a dummy grinding amount generating means from an actually measured dimension, calculating the predicted dimension of an article to be machined and adjusting the feeding amount of a grinding wheel based on the calculated predicted dimension. SOLUTION: Because of a change from rough to precise grinding based on a predicted value, a work is prevented from being ground over a P2 signal point (P2 signal outputted from a determination output section) by rough grinding, and the inconvenience of the ground margin of precise grinding caused by rough grinding is prevented. When a grinding operation is changed from rough to precise grinding, the amount of feeding a grinding wheel to the work is reduced compared with that in the case of rough grinding, and a work dimension reduced during one period of a traverse grinding cycle is reduced compared with that in the case of rough grinding.  Also, when the operation is changed to precise grinding, dummy data outputted from the dummy data output section 28 of a control section 20 to a predicted value calculation section 24 is also changed to dummy data set from rough grinding to precise grinding, and a reduction in the predicted value is also small.

Title: Steel plate cooling device
Inventor: YAMANE KIYOSHI
IPC: C21D1/00
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent a header tank and a slit nozzle from deformation and a crack without generating any high stress in a steel plate cooling device by discharging air from a check valve into the atmosphere when the air pressure within the header tank becomes a given pressure or above. SOLUTION: When opening a cooling water shut-off valve 7 and starting water supply to the header tank 2, since a nozzle shutter 5 and the check valve 6 are closed, the air pressure within the header tank 2 is risen in accordance with the increase of the cooling water. When the air pressure becomes a given pressure or above, the check valve 6 is opened and air is discharged into the atmosphere. When opening the nozzle shutter 5 and starting the cooling of the steel plate, the air pressure within the header tank 2 is changed into a negative pressure, the check valve is closed and the cooling water becomes a stable laminar flow accompanied with the outflow of the cooling water from the slit nozzle 3. By this way, the generation of the high stress in the whole steel plate cooling device is prevented without rising the air pressure within the header tank 2.

Filed: 1993-05-07
Abstract: PURPOSE:To suppress a decrease in heat transfer performance due to frosting and to extend an operating time of a refrigerator by disposing electrodes at front and rear sides of a cooler and applying high voltages having different polarities to the electrodes, respectively. CONSTITUTION:Voltages having different polarities are applied to electrodes 3 of a cooler 1 to form an electric field 6 in an entire cooling surface of the cooler 1. That is, since the strong field 6 is concentrically formed at a fin end 18 of the cooler 1, the field 6 is effectively operated against frosting of the end 18 for causing an air flow passage 4 to be blocked thereby to suppress concentrically frosting at the end 18. Thus, a decrease in heat transfer performance due to the frosting can be suppressed, and an operating time of the refrigerant can be extended.
